Improvement in flour-bolts

REBECCA J. MOETELAND, OE NEvADA, MISSOURI, ADMINISTRATRIX Or JOSEPH C. KAUEMAN, DECEASED.

'IMPROVEMENT IN FLouR-BOLTS.

Specification forming part of Lettere Patent No. 143,910, dated October 21, 1873 application filed April 11,1873.

To all whom it may concern:

Be it known that JOSEPH G. KAUFMAN, of Nevada, in the county of Vernon and State of Missouri, did invent certain new and useful Improvements in Flour-Bolts 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tO the accompanying drawing and to the letters Of reference marked thereon.

The nature of this invention consists in the construction and arrangement of a revolving flour-bolt with interior beaters revolving in the opposite direction from that of the bolt, as will be hereinafter more fully Set forth.

AIn order to enable others skilled in the art to which this invention appertains to make anduse the same, I will now proceed to describe its construction and Operation, referring to the annexed drawing, which forms a part of this specification, and in which- Figure l is a longitudinal vertical section, and Fig. 2 a transverse vertical section, of the flour-bolt.

A represents the frame-work, wit-hin which the bolt B is placed. This .bolt may be constructed in any of the known and usual ways, and is supported byhollow journals a a in the Jame A. Through the bolt B passes a shaft, b, which also passes through and has its bear-` ings in the hollow journals a a; and on said shaft, within the bolt, is secured a triangular or other suitably-shaped roller, C, extending nearly if not quite the entire length of the bolt. Near each end of th roller C are a series of arms, d d, attached to it, and extending radially from it. The corresponding arms at the two ends of the cylinder are connected by wires t' i, each set thus forming a beater within the bolt. One or more of these beaters may be used, as desired, and they may be attached direct to the shaft without the use Of the roller C. Upon the outer end of one of the hollow journals cis attached a large geanwheel, D, and on the shaftb, at the saine end of the machine, is attached a smaller gear-\vheel, D1; and these two wheels gear with similar wheels D2 and D3, respectively, attached to a vertical shaft, E, which may be revolved by any suitable ineans. Under the bolt is a hopper, G, which is to have a conveyer in its bottom.

The gearing above described is so constructed that the beaters run in the Opposite direction tO the bolt, and make two revolutions to one of the bolt. The beaters act upon the iiour within the bolt, and prevent it from forining into balls, and also keeps the light particles (as iibers of the grain, Src.) up, preventing it from passing through the cloth, which, therefore, passes out at the end of the bolt, leaving only the pureflour to pass through the meshes of the cloth, making the flour pure, clear, and white, and improving it from one to three grades.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with the bolt B, the wire beater constructed as shown, and revolving in a direction Opposite to that Of the bolt, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this V15th day of March, 1873.
